[BJS2-B05-SW02-25GE0/0/5]quit # 退出vlan
2.2 调整辅测端交换机vlanif
1. 查看vlan 1188 的 Vlanif info
[BJS2-B05-SW02]interface Vlanif 1188
[BJS2-B05-SW02-Vlanif1188]dis th
#
interface Vlanif1188
#
return
[BJS2-B05-SW02-Vlanif1188]
2. 配置Vlanif IP
[BJS2-B05-SW02-Vlanif1188]ip address 33.33.33.119 255.255.255.0
[BJS2-B05-SW02-Vlanif1188]dis th
#
interface Vlanif1188
ip address 33.33.33.119 255.255.255.0
#
return
2.3 调整辅测端mac0 口IP
辅测端mac0 口IP 应该与 mac0 口连接的SW 口所在的vlanIf IP 同网段，
所以删除辅测端mac0 口IP，并重新配置辅测端mac0 口IP
1. 修改mac0 iP 前查看
[root@localhost network-scripts]# ifconfig swift150f0
swift150f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 11.11.11.219 netmask 255.255.255.0 broadcast 11.11.11.255

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
[root@localhost network-scripts]#
2. 修改mac0 IP
[root@localhost network-scripts]# cat /etc/sysconfig/network-scripts/ifcfg-swift150f0
HWADDR=74:3E:39:10:02:57
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=none
IPADDR=33.33.33.219 # 修改IP为33.33.33.219
PREFIX=24
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV4_DNS_PRIORITY=100
IPV6INIT=no

UUID=a8bd1d0a-be3d-4fc2-a3fb-fe027e17e7bd
DEVICE=swift150f0
ONBOOT=yes
[root@localhost network-scripts]#
3. 修改后使iPv4 生效
[root@localhost network-scripts]# systemctl restart network
[root@localhost network-scripts]# ifconfig swift150f0
swift150f0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 33.33.33.219 netmask 255.255.255.0 broadcast 33.33.33.255

TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
[root@localhost network-scripts]#
2.4 辅测添加route配置
e3. SW(主测端)调整
3.1 调整主测端交换机vlanif
#因为mac0 连接SW 0/0/1 口，所在vlan:1021
1. 查看vlan 1021 的 Vlanif info
[BJS2-B05-SW02-Vlanif1188]interface Vlanif 1021
[BJS2-B05-SW02-Vlanif1021]dis th
#
interface Vlanif1021
#
return
[BJS2-B05-SW02-Vlanif1021
2. 配置Vlanif IP
[BJS2-B05-SW02-Vlanif1021]ip address 11.11.11.118 24
[BJS2-B05-SW02-Vlanif1021]dis th
#
interface Vlanif1021
ip address 11.11.11.118 255.255.255.0
#
return
[BJS2-B05-SW02-Vlanif1021]
3.2主测添加route配置
1. 添加route 前查看

2. 添加route
# route add -net <三层环境vlanif 网段>/24 gw <本机SW 口所在vlanif IP>
e.g: route add -net 33.33.33.0/24 gw 11.11.11.118
[root@localhost wangkatool]# route add -net 33.33.33.0/24 gw 11.11.11.118
